GE IS200VAICH1C Mark VI Analog Input/Output Board

IS200VAICH1C supports twenty analog inputs and four analog outputs when used with two matched terminal boards. The VAIC processor connects those field signals to the Mark VI VME control architecture.

IS200VAICH1C is documented with TBAIH1B or earlier terminal boards and with all DTAI revisions. GE describes a different terminal-board requirement for the later VAICH1D generation.

IS200VAICH1C supports up to 500 Ω on the documented 4–20 mA output circuits with matching terminals. The 800 Ω value belongs to the later VAICH1D generation and must not be substituted for H1C.

IS200VAICH1C uses the VAIC input spans documented as 4–20 mA, ±1 mA, ±5 Vdc and ±10 Vdc. The connected terminal-board circuitry and configured input type must match the field signal.

IS200VAICH1C is documented with a normal 10 ms scan, a sixteen-bit input converter with fourteen-bit resolution, and a twelve-bit output converter. GE lists input measurement accuracy better than 0.1% full scale.

IS200VAICH1C is the H1C generation. VAICH1D and later versions use TBAIH1C or later, or STAI, with different output-drive capability; they should not be treated as an unqualified board-only substitution.
